J.C. Whitney JT960924 Downstream Heated Oxygen Sensor 4-Wire OEM Replacement

The J.C. Whitney JT960924 is a direct-fit, heated downstream oxygen sensor (O2 sensor) designed as an OEM-style replacement. Positioned after the catalytic converter, this downstream sensor monitors exhaust gas oxygen content and reports data to the engine control module, helping maintain optimal fuel trim and emissions compliance.

Engineered for a direct, no-modification installation, this 4-wire heated sensor features the correct OEM-style connector, proper wire length, and threaded mounting style for a straightforward swap with no cutting or splicing required.

Key Features:

• Direct-Fit Design — OEM-style connector and correct wire length for plug-and-play installation
• Heated Sensor — Built-in heater circuit ensures fast warm-up and accurate readings from cold start
• 4-Wire Configuration — Two heater wires and two signal wires for full heated sensor functionality
• Downstream Position — Installs after the catalytic converter (Bank 1, Sensor 2) to monitor converter efficiency
• Threaded Mounting — Standard threaded installation into the exhaust bung; no special tools required
• OEM Replacement Quality — Manufactured to meet or exceed original equipment specifications

Replacing a failed downstream O2 sensor can resolve check engine lights, improve fuel economy, and restore proper emissions system function. The J.C. Whitney JT960924 provides a reliable, cost-effective alternative to dealer-sourced parts.
